Since the last Android 11 System Update on 15/6/21 for my Samsung A50 phone I am unable to connect to the internet via data. Connecting via Wi-Fi is fine but not by data. Some apps like Twitter still work, but all browsers including Chrome, and other Apps like Youtube, Facebook etc will not connect to the internet via data. I have swapped my Vodafone SIM card but this hasn't helped. I have cleared cache for all apps and browsers. Any suggestions?
